Although public relations scholarship has often discussed the possibilities of dialogue and engagement using social media, research has not truly explored this dynamic. Instead, research on social media platforms has focused on measuring the content and structure of organizational profiles. This study seeks to enhance the field's discussion about social media engagement by determining what organizational content individual stakeholders prefer on Facebook in terms of liking, commenting, and sharing. A content analysis of 1,000 updates from organizations on the Nonprofit Times 100 list indicates that, based on what they comment on and like, individuals prefer dialogic, as well as certain forms of mobilizational, messages; however, they are more likely to share one-way informational messages with their own networks. These findings are interpreted using practical and theoretical implications for the practice of public relations. 相似文献

The operating microscopes may be a significant cause of fatigue and discomfort in surgeons. The need for the microscope to be placed over the operating field forces surgeons to remain at the microscope's eyepieces at an uncomfortable posture for the entirety of the surgery. This study compared the effects on microsurgical task performance for four visualization methods: a monocular microscope, a binocular microscope, a three-dimensional (3D) flat-panel television display and a two-dimensional (2D) flat-panel television display. Eleven subjects each performed two microsurgical tasks and their performance was documented by video camera. The statistical analysis performed indicated utilization of the microscope as a visualization method increased subject performance. No significant difference in performance between the 2D and stereoscopic visualization methods. 相似文献

Homeless youth lack the traditional support networks of their housed peers, which increases their risk for poor health outcomes. Using a multilevel dyadic analytic approach, this study identified characteristics of social contacts, relationships, and social networks associated with the provision of tangible and emotional support to homeless youth (N = 419, M age = 20.09, SD = 2.80). Support providers were likely to be family members, sex partners, or non–street‐based contacts. The provision of support was also associated with contacts' employment and homelessness status, frequency of contact, shared risk behaviors, and the number of network members that were homeless and employed. The results provide insights into how homeless youth could be assisted to develop more supportive social networks. 相似文献

In clinical trials, missing data commonly arise through nonadherence to the randomized treatment or to study procedure. For trials in which recurrent event endpoints are of interests, conventional analyses using the proportional intensity model or the count model assume that the data are missing at random, which cannot be tested using the observed data alone. Thus, sensitivity analyses are recommended. We implement the control‐based multiple imputation as sensitivity analyses for the recurrent event data. We model the recurrent event using a piecewise exponential proportional intensity model with frailty and sample the parameters from the posterior distribution. We impute the number of events after dropped out and correct the variance estimation using a bootstrap procedure. We apply the method to an application of sitagliptin study. 相似文献

This article evaluates a program between students at a primary school and aged care residents. The aim of the program was to increase respect and appreciation between the groups. Visiting programs between children and the elderly are well documented, and assumes that the contact will benefit both groups. However the research is contradictory. To ensure that this program was achieving its goals, pre-post test data using the Children’s Perceptions of Aging and Elderly test was collected. Significant improvements in attitude were seen in two items. Overall, there was an improvement in attitude in 12 of the 18 instrument items. 相似文献

Background
While the provision of maternity education across the perinatal period can increase the confidence and self-efficacy in childbearing women, there is still thought to be a lack of effective educational resources for parenthood. This study, conducted in Victoria, Australia, investigated women’s experiences of, and attitudes to education communicated in maternity service provision.Methods
189 women were recruited from a variety of settings to participate in a mixed-methods survey about their experiences of perinatal health service education.Findings
Of the sample of childbearing women, 153 (81%) reported attending antenatal classes. Women perceived their antenatal education as beneficial, though many women still felt unprepared beyond labour and birth. With respect to the hospital postnatal stay, findings suggested a variation among the content imparted to women across different Victorian maternity services, (e.g. rural women tended to be more dissatisfied with information received in relation to maternal emotional and physical health). Overall, women wished they had been more informed about breastfeeding and settling techniques, while a lack of information relating to social support initiatives for the postnatal period was also indicated. Women reported that they were missing educational and practical reinforcement of mothercraft skills.Conclusions
There is a need for a reorientation of perinatal health service education. A health promotion approach is suggested as it extends beyond the physical recovery from birth to encompass psychosocial factors; including perinatal morbidities that can disrupt the quality and experience of the transition to parenthood. 相似文献49.

Objective: To investigate sexual orientation differences in college men's motivations for HIV testing. Participants: 665 male college students in the Southeastern United States from 2006 to 2014. Methods: Students completed a survey on HIV risk factors and testing motivations. Logistic regressions were conducted to determine the differences between heterosexual men (HM) and sexual minority men (SMM). Results: SMM were more motivated to get tested by concern over past condomless sex, while HM were more often cited supporting the testing program “on principle” and wanting a free t-shirt. SMM and HM differed in behaviors that impact HIV risk and other demographics. However, differences in testing motivation by concern over past condomless sex or wanting a free t-shirt persisted when controlling for these demographic and behavioral differences. Conclusions: Appropriately designed HIV prevention interventions on college campuses should target SMM's distinct concern over past condomless sex as a testing motivation. 相似文献
